daemon-to-be-activatable/22912

Snapped applications are unable to trigger the mate-notification-daemon
due to the service file not specifying an assumed apparmor label so
apparmor does not know that it is unconfined and thus may receive the
dbus calls. Snapd specifies in the apparmor policy that the label must
be "unconfined".

I've filed an upstream PR to fix this at https://github.com/mate-
desktop/mate-notification-daemon/pull/201
